Hey, you may have a try of the SQL Reporting Services control which helps to use the dll assembly for barcode generation. It is something like the integrated component, make sure it compatible with your SQL and support the linear barcode you need.

A third control < a href="http://terrek.com/products/reporting_service_barcode/">barcode printer for Reporting Service</a> generates barcode images maintain when export to Excel. Free trial versions are provided.
